No vaccines, including Polio, have ever been federally mandated

Immediately following the government's licensing of the Salk vaccine, the National Foundation for Infantile Paralysis [Refer to the Statement by the President on the Polio Vaccine Situation-May 31, 1955 - the Federal Government will assume responsibility for the equitable allocation of the vaccine among the States] contracted with private drug companies for US$9 million worth of vaccine (around $87 million today) – about 90% of the stock. They planned to provide it free to the coountry's first and second graders.

But just two weeks after the first doses were administered, the Public Health Service reported that six inoculated children had come down with polio.

In those hopeful first few weeks of the polio vaccine distribution, those of us lining up for shots had little to fear beyond the sting of an injection. That changed quickly. But just two weeks after the first doses were administered, the Public Health Service reported that six inoculated children had come down with polio.

As the number of such incidents grew, it became clear that some of the shots were causing the disease they were meant to prevent. A single lab had inadvertently released adulterated doses.

After considerable fumbling and outright denial, Surgeon General Leonard Steele first pulled all tainted vaccine off the market.

Once some children had in fact been harmed by the shot, obfuscation by government officials, clumsy explanations and delayed responses engulfed the entire production and distribution process in confusion and suspicion. Trust in the government and the vaccine eroded accordingly. Gallup polls found that by June 1955, almost half of the parents who responded said they would not take any further vaccine shots...

Federal jurisdiction over public health matters derives from the Commerce Clause of the United States Constitution, which states that Congress shall have the power [t]o regulate Commerce with foreign Nations, and among the several States ...

Congress has enacted requirements regarding vaccination of immigrants seeking entry into the United States, and military regulations require American troops to be immunized against a number of diseases. The Secretary of Health and Human Services has authority under the Public Health Service Act to issue regulations necessary to prevent the introduction, transmission, or spread of communicable diseases from foreign countries into the states or from state to state.

Current federal regulations do not include any mandatory vaccination programs; rather, when compulsory measures are needed, measures such as quarantine and isolation are generally utilized to halt the spread of communicable diseases.

In 1922, the Supreme Court again reiterated this stance in the case of a Texas anti-vaxxer, reminding us, "it is within the police power of a State to provide for compulsory vaccination."...

By 1969 compulsory immunization laws in twelve states - Georgia, Hawaii, Illinois, Kansas, Kentucky, Louisiana, Masssachusetts, Michigan, Mississippi, Rhode Island, Tennessee, and West Virginia - had expanded to include smallpox, measles, poliomyelitis, diphthheria, pertussis, and tetanus. Meanwhile, seven states - Arizona, Caliifornia, Minnesota, North Dakota, South Dakota, Utah, and Washington - found it unlawful to compel citizens to be vaccinated for smallpox while still requiring pre-enrollment immunization for other diseases like measles.

The Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices Trusted Source issues a list of recommended childhood vaccinations that states generally follow.

All 50 states mandate vaccination as a condition of entry into school, although exceptions vary from state to state.

In addition to mandating vaccination against childhood diseases like polio, diphtheria, and measles, three states — Rhode Island, Virginia, and the District of Colummbia — also have passed laws requiring school-aged children to get vvaccinated against the HPV virus,

[...] The free distribution of the Salk vaccine would be ending in June 1957 and the departments recommended that anyone under the age of 40 take advantage of program of vaccinations taking place every Friday and Saturday before it was closed down.

It was a different story in June 1959 when both commissioners issued a statement noting the "Area's apathy toward polio shots held shame, and sounded the alarm that many parents weren't completing the three-shot inoculation..."
